SPECIFICATION forming part of Letters Patent No. 287,531, dated October30, 1883.

Application filed July 10, 1883. (No model.)

in the construction of the samehaving for i their object to produce adevice which shall possess superior advantages in point of simplicity,durability, ease of adjustment for any desired purpose, and generalefficiency, all as will be hereinafter fully described, and particularlypointed out in the claim.

In the drawings hereto annexed, Figure 1 is a perspective View. Fig. 2is a longitudinal vertical sectional View. taken through the stock orframe of the machine. Fig. 3 is a horizontal sectional view of the same,and Fig. 4 is a rear view.

The same letters refer to the same parts in all the figures.

A in the drawings designates a rectangular frame, which is provided witha centrally-located clip or bail, B, the arms of which, 0 O, extendv infront of thesaid frame. D is the beam or tongue,-which is pivotedbetween the arms 0.0 by means of a bolt, E. To the sides of said beamare secured wings or castings F F, having perforations G, in which arehooked rods H, the/inner or rear ends of which are screw-threaded, asshown. To the frame A are secured straps I, having forwardly-proj ectingperforated lugs or ears J, in which are hooked rods K, the front ends ofwhich are screw-threaded and connected by right and left hand threadednuts L with the rods H. By this construction the connecting-rods on eachside of the beam may be extended or contracted, thus enabling the beamto beheld securely at any desired angle to the frame. The under side'ofthe frame A is provided with inwardly-projecting flanges M, serving tosup;

port a series of blocks, N, the sides of which are provided with angularrecesses O. The

'ends of the frame are provided with strong set-screws P, by means of.which the blocks may be tightened together, so as to bind and retainsecurely in position the standards Q, which are fitted in the angularrecessesin the sides of the said blocks. Washers may be placed betweenthe blocks, so as to adapt the 5 frame to two, three, or more of thestandards. The latter may, by tightening the set-screws, be retainedsecurely. in place. Byloosening the set-screws they may be adjustedvertically to any desired extent. The lower ends of the standards carrythe harrow or cultivator blades R, of substantially the constructionshown in the drawings.

The'operation of my invention will be readily understood from theforegoing description, taken in connection with the drawings hereto Thecombination of the rectangular frame having inwardly-projecting flangeson its under side, the blocks fitted in said frame, and having angularrecesses in their sides, the standards fitted in the angular recessesbetween the said blocks, and having the harrow or cul- 8o tivator bladesat their lower ends, and the tighteningscrews in the ends of therectangular frame, all arranged and operating substantially as setforth. I

In testimony thatVI claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.
